20. Years in College Listed below are the numbers of years it took for a random sample of college students to earn bachelor's degrees (based on data from the National Center for Educa- tion Statistics). Construct a 95% confidence interval estimate of the mean time required for all college students to earn bachelor's degrees. Does it appear that college students typically earn bachelor's degrees in four years? Is there anything about the data that would suggest that the confidence interval might not be a good result? 4 4 4 4 4 4 4.5 4.5 4.5 4.5 4.5 4.5 8. 9. 13 13 15
